Closer. But as is common with bugs, you often don't know how long it will take to fix until you've fixed it.

I personally don't think so, but any flight stability improvement are always Welcome.
They do have the data of the beta testing. It is in there hands now.

The maximum reccomended flight weight is <1300Grams

I don't think that is going to have any bearing on our issue. But as always, early adopters should test it out to be sure. I am still on 1.08 and shall be staying there until there's a firmware with some hope!

Side note, I will be in Chicago next week and the Phantom will be joining me so I can see what it's like to not have to correct for the hook all the time and to prove (again) that this problem exists in every P2 out there.

I believe they are based in Shenzhen which is -2 degrees so they would not see any hook. They do have a Los Angeles office but it seems to be mostly few entry-level support staff. Remember, we have all sent them data to analyze.

Update in Beta Testing Progress - Sent from DJI on Sunday, May 4

Hi, Shane,

Thanks for your help, and we need you do another test with your phantom2.
Before the test, basic calibration is necessary.

Test 1:
(1) gps mode, fly a little high, hover for a while, then change to Atti mode, hover for a minute, back to gps mode again.

Test 2:
(1) set the basic gain a little low, （30%,30%）, follow the step in test 1.

Test 3
(1) Set the basic gain (20%,20%), follow the step in test 1.

So we need three data. Thank you!

Best regards,

Zach

I will be testing and sending data to Zach and Ianwood Tomorrow 5/6/14.
Just thought I would share with you all.
Keep you blades spinning

I don't understand why they wanted you to do those tests. I don't see how they would be related to the compass issue. Still waiting for Terry and Zach to come back to me and confirm that they have all the results from everyone and to find out what they've seen so far.

This Toilet bowl effect and not flying straight is questioning my confidence in dji. Was flying today and attempted a "dronie" i almost crashed due to the toilet bowl effect.... it really stinks... no pun intended...
Efter nearly crashing i landed and stored the phantom, having a fully charged battery left to fly, I was to scared to fly.

i have a $800 paper weight....
Frustrated and feeling cheated-

So, No news from DJI?
It´s a shame how long they are taking to resolve this serious issue. :shock:
